misfire #2 cylinder
Looking for help with a 2006 JCW It has a misfire on #2 cylinder We have replaced the Plugs, Plug Wires and the Coil pack... This did not fix the issue, So I removed #2 and #4 injectors and swapped them to see if the problem would move. it did not. So I connected my Noid light and started the car it pulsed for a few seconds then quit. So logic would say that the ECU was bad. Well bought a unlocked ECU put it in the car and started it ran fine shut the car off and restarted it. Car ran for a few seconds and started misfiring on #2 cylinder again.... I am lost...... Please Help
